The fifth generation (5G) mobile communication technology will be used in 2020s. One of the most important goals of 5G technologies is that it supports connectivity to anyone or anything at anytime, anywhere. For 5G systems, several technologies such as millimeter wave (mmWave) communications, massive Multiple Input Multiple Output (MIMO) communications, and vehicle to vehicle (V2V) communications are being investigated. These technologies bring with new propagation characteristics and certain requirements in the channel modelling stage. Channel modelling is indispensable because it provides information about system design, performance evaluation, efficiency and accuracy. For this reason, various channel modelling is urgently needed for 5G systems. In this study, we will first summarize the requirements for 5G channel modelling and then extensively examine the recent channel models. Eventually, a viewpoint will be provided for future research on channel models.
